I've also heard a guy, from Australia, say his dog lived to 28. The reason is he fed his dog vegetable stew everyday. No meat, raw or cooked, just vegetables.
The most recent record for the oldest dog was held by Butch, a 28-year-old from America who died in 2003
I could be mistaken, but I think there was an Australian Cattle dog (Blue Heeler) that lived 26 years.
Dog doesn't live for so long and if are saying the right thing here, it's really amazing isn't it?
